Abstract (en)
Upon receiving a transmit request REQ1 from a client apparatus (1), the server 11 transmits a group address INF1 to the client apparatus (1). The server 11 transmits block X1, which is the first block among blocks X1 through X4 resulting from subdividing the requested information, to a network 10 by specifying the group address INF1. If the server 11 receives a transmit request REQ2 from a client apparatus (2) after transmitting block X1 to the client apparatus (1), the server 11 transmits a group address INF2 to the client apparatus (2). The server 11 transmits to the network 10 the second through the fourth blocks, X2 through X4, by specifying group addresses INF1 and INF2. Furthermore, after the server 11 has transmitted the fourth block, block X4, the server 11 proceeds to transmit to the network 10 the block X1 by specifying the group address INF1, and finishes the transmission process. <IMAGE>
